I get an access violation when I run the "vault.py"
script and drag the sliders back and forth.

I've located this code:

void uiFreeBlock(uiBlock *block)
{
uiBut *but;

if(block->flag & UI_BLOCK_BUSY)
{
printf("attempt to free busy
buttonblock: %p\n", block);

...

if I append a return; right after the printf
statement, the access violation dissapears, instead
the sliders are sluggish and after a while I get a
Python22.dll error.

I'll try to investigate further why the block is BUSY
when code is called, but the code is _very_ hard to
follow, (and yes I'm a wannabie programer!), so will
see how far I'll come.
